The Booleans can be represented as string, in order to accept Boolean value from the command line arguments. If the key `optname` is present in the dictionary `options` and is not associated with a Boolean, raise an `OptionError`. If it is absent, `default` is returned instead. The valid string values for ``True`` are ``1``, ``yes``, ``true`` and ``on``, the ones for ``False`` are ``0``, ``no``, ``false`` and ``off`` (matched case-insensitively). � Invalid type � for option z%; use 1/0, yes/no, true/false, on/off)�1Zyes�true�onT)�0�no�falseZoffF�Invalid value )r � isinstance�bool�intr r r �r r r r r r r � get_bool_opt5 s r( c C s^ | � ||�}zt|�W S ty td|�d|� d��� ty. td|�d|� d���w )z?As :func:`get_bool_opt`, but interpret the value as an integer.r r z ; you must give an integer valuer# )r r& � TypeErrorr � ValueErrorr' r r r � get_int_optR s �r+ c C sJ | � ||�}t|t�r|�� S t|ttf�rt|�S td|�d|� d���)z� If the key `optname` from the dictionary `options` is a string, split it at whitespace and return it.
